<p>The X and Y axes indicate the relative Hoechst fluorescence units and number of <i>H. pylori</i> cells, respectively. Dotted vertical lines indicate genome equivalents. The main fluorescent signal of wild-type <i>H. pylori</i> was considered as one genome equivalent, as described <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033310#pone.0033310-ZawilakPawlik1" target="_blank">[39]</a>.
